Include 4 Arm Spider with Triple Chainring Support

If this item is included with the order along with an ERider T17 using the four arm spiders, we will be sure to pick one of the older spiders that still has the inner 64mm BCD 4 bolt pattern for a granny gear chainring.  Otherwise by default we ship with a spider that only supports up to a double chainring with the outer 104mm BCD bolt pattern.
